Compass in the lower left is showing 90 degrees to the one in the box on lower right.

No - that's wrong. The aircraft is facing southwest. The video feed, map and radar are all consistent and showing the heading as SW.

Compass is calibrated correctly, just getting magnetic interference.

Actually the error message is a data feed error, so it's not necessarily magnetic interference. The DAT log event stream would detail the actual problem.

Hopefully he will post it on the forum.

Its asking him to calibrate the compass. To me, thats like an idiot light on a car. Sometimes it doesnt accurately identify the problem.

Sorry gang. He already posted this thread:

Compass data error w/screenshot

Crashed my MPP and got it back up and going with a gimbal ribbon cable. Took it out for a test flight this evening and I flew it out about 2000 feet and hit RTH, done everything it should. When it got back as it hovered preparing to land I got the error that is in the screenshot. So I...

Yes - that message was likely there for the entire flight. It's an MPP, so not a time or distance trigger, but it also doesn't necessarily mean anything more than one of the magnetometers reporting an out-of-bounds value. That could be something magnetized on the aircraft. The mobile device DAT file will have the raw magnetometer data from both compasses, which should be pretty conclusive.

Yes - already discussing it over there. Should probably consolidate.

Wish we could do that now but can’t since the forum changed and being it was already posted before this
lets just continue with his thread .
